Q: I'm a contributor and not a committer. How do I participate in this process?
A: We will attempt to add a way to pull the source code from github as well. In the mean time, you should submit your changes as a patch via the review board. A reviewer will start a branch, apply the patch, wait for CI to pass, and merge it in for youYou can send a pull request on github. When two other collaborators give a LGTM, a committer will merge your pull request.
